Question

You increase the size of a page by50%. Then you decrease it by 50%. What is the size of the page now?

Answer 1

75% of original

100%+50%=150%÷2=75%

Answer 2

The increase in the original size of the page is
`75\%`

Solution:

There will be no proper solution for this problem as no dimensions are provided for the page. Moreover there is no proper mention of exactly what is increased for the page. Hence we cannot find the proper value of the size of the page.

Just for assumption let’s say the size of the page is x,

If the size increased by 50\% then the size of the page is
`\left((150 x)/(100)\right)`

Again the size of the page decreased by
`50\%`

So the size of the page now will be
`\left((150 x)/(100)\right)-\left((150 x)/(100) * 0.5\right)=\left((150 x)/(100)\right)-\left((75 x)/(100)\right)=(75 x)/(100)=75 \% \text { of } x`

So, the size of the page will be
`75 \%` of the original size.
